Hi Scott (and David),

I'm finally getting around to looking closely at the JSON patches
(hurrah!). Here are some comments:

I think we've all agreed to use --output for selecting what to print and
to instead use --format for how to format it. I also think David's got a
patch to change that, but if we have to change the current patch anyway,
we might change that at the same time.

I know I didn't contribute any code to this file, so my name shouldn't
be here. Scott, I imagine you have made some non-trivial contributions
so your name (or suitable copyright-claiming entity) should be here.

Same thing here.

Thanks for attributing the source here, but let's please keep all the
copyright statements up at the top of the file.

It would still be reasonable to have a comment at this point that this
particular code came from Dave Gamble and cJSON. But it should also
mention the license under which the code is being integrated.

I suggest leaving the notmuch-standar GPLv3+ blurb at the top of the
file, but then quoting the license itself of the external code, (it's a
short MIT-style license, right?).

It would be nice to have a little comment here describing what the
function does, (what characters get quoted and how, that the return
value is talloced with 'ctx' as a parent, and perhaps a pointer to the
appropriate JSON reference/specification).

But I definitely like this nice little function as opposed to some JSON
library. Thanks!

Definitely missing at least a quick comment for internal documentation
here as well. But I do like the way this works.

Thanks for adding the documentation here. But please add to notmuch.1 as

This all looks really great. And I can't wait to apply it and play with
it more.
